566 REVISION OF THE AMYCTERID.E, 



Hah. — Clarence River(Macleay Museum) — Queensland : Kil- 

 larney(R. Illidge). Type in Macleay Museum. 



Closely allied to P. variolosa, but differing in the anal excava- 

 tion. There is a species from Walcha, N.S.W., in my collection,. 

 which may be a variety; it differs in having the fascicles rather 

 closer together, the intermediate bristles not so widely separated 

 fiom the posterior row, and of a black colour.

^. Of a short, subparallel form, convex. Prothorax finely 

 granulate; elytra foveo-striate, interstices granulate; fascicles 

 moderately far apart, forceps and laminae rather small. Black, 

 opaque, rather sparingly clothed with minute greyish scales; 

 mandibles, sides of metasternum, and first and second ventral 

 segments more closely clothed with yellow scales; legs rather 

 densely clothed with white scales interrupted with dark setse> 

 setae dark brown; fascicles dark brown, anal hair black.

 groove present in front. Rostrum short, ridges somewhat 

 flattened, basal impressions well defined, median notch present;

 mentum not noticeably thickened in middle, sparingly bearded; 

 mandibles with outer portion lipped in front and densely clothed 

 with short yellow scales interspersed with longer darker hairs. 

 Prothorax as wide as long(6 x 6 mm.), widest about middle, 

 evenly narrowed to base and apex; median lobe strongly produced; 

 collar-constriction moderately marked above, median line faintly 

 impressed near base, also a faint impression near lateral basal 

 angle; finely granulate, granules rather smaller in centre, each 

 with a large setigerous puncture. Elytra oblong(12 x 8 mm.),, 

 lightly rounded on sides, widest behind middle, strongly declivous; 

 apex mucronate, flange small; base arcuate, shoulders prominent; 

 irregularly striate, striae very uneven, shallowly foveate; inter-
